Abstract: Various examples are provided related to improvements in generalized flow profile production. In one example, a method includes determining a downstream flow profile including a pressure profile and a velocity profile; fabricating a pressure profile generator including distortion screen(s) disposed on a backing structure; fabricating a velocity profile generator including turning vanes in a flow path through the velocity profile generator that are configured to generate the velocity profile; attaching the pressure profile generator to an input side of the velocity profile generator; and installing the flow conditioning device in the flow field of interest. Flow through the flow conditioning device produces the downstream flow profile in the flow field of interest.

Abstract: A system and method of non-intrusive anemometry. The system comprises an acoustic transmitter disposed at a boundary of fluid flow and first and second acoustic receivers adapted to receive transmissions from the acoustic transmitter. A processor is coupled to the acoustic receivers to determine the time of arrival of the transmission at the acoustic receivers. The acoustic transmitter and acoustic receivers are arranged such that the acoustic transmitter is upstream from the first acoustic receiver which is in turn upstream from the second acoustic transmitter.

Abstract: An asymmetric tetrahedral vortex generator that provides for control of three-dimensional flow separation over an underlying surface by bringing high momentum outer region flow to the wall of the structure using the generated vortex. The energized near-wall flow remains attached to the structure surface significantly further downstream. The device produces a swirling flow with one stream-wise rotation direction which migrates span-wise. When optimized, the device produces very low base drag on structures by keeping flow attached on the leeside surface thereof. This device can: on hydraulic structures, prevent local scour, deflect debris, and reduce drag; improve heat transfer between a flow and an adjacent surface, i.e., heat exchanger or an air conditioner; reduce drag, flow separation, and associated acoustic noise on airfoils, hydrofoils, cars, boats, submarines, rotors, etc.

Abstract: Disclosed is a manufactured three-dimensional convex-concave fairing with attached vortex generators, for hydraulic structures such as bridge piers and abutments, whose shape prevents the local scour problem around such hydraulic structures. The device is a conventionally made concrete or fiber-reinforced composite, or combination of both, vortex generator equipped hydrodynamic fairing that is fit or cast over an existing or new hydraulic structure around the base of the structure and above the footing. The vortex generators are positioned so as to energize decelerating near wall flow with higher-momentum outer layer flow. The result is a more steady, compact separation and wake and substantially mitigated scour inducing vortical flow.
